Separating, disintegrating, and mixing apparatus



Patented .lune 24, 1930 UNITED STATES EUGNE DE DORLODOT, OF IPARIS, FRANCE SEPARATING, DISINTEGRATING, AND MIXING APPARATUS Application led November 13, 1928, Serial No. 319,087, and in lFrance November 18, 1927.

The present invention has for its subject a separating-disintegrating-miXing apparatus for all kinds of applications but more particularly applicable to the treatment of ores and similar materials.

This apparatus is essentially characterized by the application, for obtaining the results aimed at, of a pneumatic elastic band iniated to a suitable pressure and mounted on a wheel to which a rotary movement is imparted by any suitable means.

The wheel provided with the band in question is combined with a trough to which the material to be treated is supplied and which 15 may also be supplied with a stream of water.

In the accompanying drawing there are illustrated diagrammatically and solely by way of example, two forms of construction in accordance with the invention.

Figure 1 shows a longitudinal section of the most simple case of construction of the apparatus.

Figure 2 shows to a larger scale a modihed form of apparatus in which the front wall of the trough has been removed, and

p Figure 3 is a plan view, partly in section,

of the apparatus shown in Figure 2.

In the form ofconstruction shown in Figure 1 the material to be treated is conveyed 3o by a steam of water which is supplied from a pipe 1, under a pneumatic tyre 2 mounted on the wheel 3. The wheel rotates in a trough 4 of which the bottom may be provided, for a suitable portion of its length, with a screen or ating 5.

he material M to be treated is drawn under the tyre and is mixed by the latter in such a manner that the fine particles are forced through the screen whilst the larger particles pass under the tyre which, by reason of its elasticity, yields so as to enable the said larger particles to ass irrespective of their size. The fine art1cles are collected in a tank 6 and are suita ly removed to the exterior.

In the form of construction shown in Figures 2 and 3 the general arrangement of the device is the same as shown in Figure 1, but the trough 4 is provided with a suitable inclination and the wheel 3 is mounted slightly eccentrically in relation to the cylindrical surface of the screen 5. In Figures 2 and 3 the reference figures indicate the same parts as in Figure 1. The bearing 7 of the shaft of the Wheel 3 is preferably arranged in silch a manner as to enable the tyre 2 to be approached or withdrawn from the inner surface of the screen 5, accordingto the degree of size of the materials treated, by introducing Wedges 8, of any suitably selected thickness.

'Ihe walls of the trough in which the elastic tyre rotates may be provided with brush mats as indicated at 9 in Figure 3. The elastic tyre may also be provided with a belt 10 of b ruIsh matting or of any other suitable materia The Wheel 1 may be driven by hand, cranks 11 and 12 being suitably mounted on the shaft thereof for this purpose as is indicated in the drawing, or the wheel may be driven by a motor, not shown.

I claim 1. A separating, disintegrating and mixing device for general application, but more particularly for the treatment of ores and similar materials comprising a rotary wheel, a pneumatic t re mounted on said wheel and adapted to e inated at any suitable pressure, a trough in which said Wheel is mounted, and a screen mounted in said trough, said tyre being adapted to force the line particles of material through said screen and to yield to the larger particles whereby these are removed from the screen.

2. A separating, disintegrating and mixing device for general application but more particularly for the treatment of ores and similar materials comprisinga rotary Wheel, a pneumatic tyre mounted on said wheel and adapted to beinlated at any suitable pres- 9c sure, a trough in which said wheel is mounted, and a screen mounted in said trough, said tyre' being adapted to force the fine particles of material through said screen and to yield to the larger particles whereby these are re- 95 moved from the screen, said screen being of concave shape Whilst the wheel is mounted eccentrically in relation thereto.

3. A separating, disintegrating and mixing device for general application, but more par- 100 ticularly for the treatment of ores and similar materials comprising a rotary wheel, a pneumatic tyre mounted on said Wheel and adapted to be inflated at any suitable pressure, a trough in which said Wheel is mounted, and a screen mounted in said trough, said tyre being adapted to force the fine particles of material through said screen and to yield to the larger particles whereby these are removed from the screen, a shaft on which said wheel is mounted, bearings in said trough for supporting said shaft, and wedge members co-operating with said bearings so as to adjust said wheel relatively to said screen.

4. A separating, disintegrating and mixing device for general application, but more particularly for the treatment of ores and similar materials comprising a rotary Wheel, a pneumatic tyre mounted on said Wheel and adapted to be inflated at any suitable pressure, a trough in which said wheel is mounted, and a screen mounted in said trough, said tyre being adapted to force the fine particles of material through said screen and to yield to the larger particles whereby these are removed from the screen, said trough having an inclined portion whereby the materials to be treated are conducted on to the screen and under said wheel.

5. A separating, disintegrating and mixing device adapted for use with a stream of water, and designed for general application, but more particularly for the treatment of ores and similar materials comprising a rotary Wheel, a pneumatic: t re mounted on said Wheel and adapted to be inflated at any suitable pressure, a trough in which said wheel is mounted, and a screen mounted in said trough, and means for hydraulically conveying materials to the screen, the said tyre beine adapted to force the line particles of materia through said screen and to yield to the larger particles whereby these are removed from the SCIGeIl.
